Hi:
When I move the Z axis it seems
to over shoot by .010" and then slowly returns to where it is
supposed to be. The DRO readouts don't relect this change. If I use
the incremental jog and make a move as little as .0005 it still over
shoots by .010 I`ve tried messing around with the adjustments on
the rutex drive but I cant seem to get it to make any difference. Is
it possible I need to make an adjustment at the servo amp itself?
I'm not loosing any position on the axis.
This sounds like either a P setting or a setting in the servo amp. What
your seeing is following error which is correcting slowly. You need more
gain I think...
